Miklos Vajna bf0d49c437 clang-rename: let -force handle multiple renames
Summary:
The use case is that renaming multiple symbols in a large enough codebase is
much faster if all of these can be done with a single invocation, but
there will be multiple translation units where one or more symbols are
not found.

Old behavior was to exit with an error (default) or exit without
reporting an error (-force). New behavior is that -force results in a
best-effort rename: rename symbols which are found and just ignore the
rest.

The existing help for -force sort of already implies this behavior.

Jonas Devlieghere 5dc87861d6 [diagtool] Change default tree behavior to print only flags
This patch changes the default behavior of `diagtool tree` to only
display warning flags and not the internal warnings flags. The latter is
an implementation detail of the compiler and usually not what the users
wants.

Furthermore, flags that are enabled by default are now also printed in
green. Originally, this was only the case for the diagnostic names.

Matt Morehouse f051f5d1e6 Integrate Kostya's clang-proto-fuzzer with LLVM.
Summary:
The clang-proto-fuzzer models a subset of C++ as a protobuf and
uses libprotobuf-mutator to generate interesting mutations of C++
programs.  Clang-proto-fuzzer has already found several bugs in
Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747,
https://bugs.llvm.org/show_bug.cgi?id=33749).

As with clang-fuzzer, clang-proto-fuzzer requires the following
cmake flags:
- CMAKE_C_COMPILER=clang
- CMAKE_CXX_COMPILER=clang++
- LLVM_USE_SANITIZE_COVERAGE=YES  // needed for libFuzzer
- LLVM_USE_SANITIZER=Address  // needed for libFuzzer

In addition, clang-proto-fuzzer requires:
- CLANG_ENABLE_PROTO_FUZZER=ON

clang-proto-fuzzer also requires the following dependencies:
- binutils  // needed for libprotobuf-mutator
- liblzma-dev  // needed for libprotobuf-mutator
- libz-dev  // needed for libprotobuf-mutator
- docbook2x  // needed for libprotobuf-mutator
- Recent version of protobuf [3.3.0 is known to work]

A working version of libprotobuf-mutator will automatically be
downloaded and built as an external project.

Implementation of clang-proto-fuzzer provided by Kostya
Serebryany.

Sean Callanan 2b3a54bafc This adds the argument --dump-ir to clang-import-test, which allows
viewing of the final IR. This is useful for confirming that 
structure layout was correct.

I've added two tests:

- A test that checks that structs in top-level code are completed 
  correctly during struct layout (they are)
- A test that checks that structs defined in function bodies are 
  cpmpleted correctly during struct layout (currently they are not, 
  so this is XFAIL).

The second test fails because LookupSameContext()
(ExternalASTMerger.cpp) can't find the struct. This is an issue I 
intend to resolve separately.

Petr Hosek 5518d189ee [scan-build-py] Patch to fix "-analyzer-config" option
I noticed that when I use "-analyze-config" option in scan-build-py, it
behaves differently from original perl based scan-build.

For example, command:

$ scan-build -analyzer-config ipa=basic-inlining make

Will work without any issues on perl version of scan-build. But on
scan-build-py it will throw an error message "error reading
'ipa=basic-inlining'".

After debugging, it turns out that the scan-build-py does not put
"-analyzer-config" flag in front of the analyzer config flags (in this
case is the "ipa=basic-inlining") in the final clang command line. This
patch fixes this issue.

This is in preparation for submitting patches for review to implement __VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective function and making it less comprehensible.

Benjamin Kramer 43c0f486b0 [Driver] Actually report errors during parsing instead of stopping when there's an error somewhere.
This is a more principled version of r303756. That change was both very
brittle about the state of the Diags object going into the driver and
also broke tooling in funny ways.

In particular it prevented tools from capturing diagnostics properly and
made the compilation database logic fail to provide arguments to the

Saleem Abdulrasool d064e91ece Revert "Revert r305164/5/7."
Restore the `-gz` option to the driver with some minor tweaks to handle
the additional case for `-Wa,--compress-debug-sections`.

This intends to make the compression of the debug information
controllable from the driver.  The following is the behaviour:

  -gz           enable compression (ambiguous for format, will default to zlib-gnu)
  -gz=none      disable compression
  -gz=zlib-gnu  enable compression (deprecated GNU style zlib compression)
  -gz=zlib      enable compression (zlib based compression)

Although -Wa,-compress-debug-sections works, it should be discouraged
when using the driver to invoke the assembler.  However, we permit the
assembler to accept the GNU as style argument --compress-debug-sections
to maintain compatibility.

Note, -gz/-gz= does *NOT* imply -g.  That is, you need to additionally
specific -g for debug information to be generated.

With this patch, one can configure a BufWrite hook that will make the
clang-format integration compute a diff of the current buffer with the file
that's on disk and format all changed lines. This should create a
zero-overhead auto-format solution that doesn't require the file to

Saleem Abdulrasool 7289ba9165 Driver: add support for `-gz` and `-gz=`
These options control the behaviour of the compression of debug info
sections on ELF targets.  Our behaviour slightly diverges from the
behaviour of GCC.  `-gz` maps to the `-compress-debug-sections` rather
than `-compress-debug-sections=zlib` or
`-compress-debug-sections=zlib-gnu`.  This small divergence allows us to
be compatible across versions of binutils (=zlib support was introduced
in 2.26, while earlier versions only support =zlib-gnu).  This also
allows users to not have to worry about the version of the assembler
they may be using if they are not using the IAS.  Previously, users
would have had to go through the internal option
`-compress-debug-sectionss` and pass that through to the assembler,
which is no longer needed.

Other llvm tools display their registered targets when showing version

To support this, D33899 adds the llvm parts, which make it possible to

a call to printRegisteredTargetsForVersion in clang's PrintVersion, and
adds a raw_ostream parameter to two other PrintVersion functions.

A suspended translation unit uses significantly less memory but on the

clang_reparseTranslationUnit to resume it or
clang_disposeTranslationUnit to dispose it completely.

This helps IDEs to reduce the memory footprint. The data that is freed
by a call to clang_suspendTranslationUnit will be re-generated on the
next (re)parse anyway. Used with a preamble, this allows pretty fast
resumption of the translation unit for further use (compared to disposal
of the translation unit and a parse from scratch).

Now if clang driver is given wrong arguments, in some cases it
continues execution and returns zero code. This change fixes this

The fix revealed some errors in clang test set.

File test/Driver/gfortran.f90 added in r118203 checks forwarding
gfortran flags to GCC. Now driver reports error on this file, because
the option -working-directory implemented in clang differs from the
option with the same name implemented in gfortran, in clang the option
requires argument, in gfortran does not.

In the file test/Driver/arm-darwin-builtin.c clang is called with
options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed
in r191435 and now clang reports error on this test.

File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.

Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.

Other revealed errors are mainly mistypes.

ASTImporter has some bugs when it's importing types 
that themselves come from an ExternalASTSource. This 
is exposed particularly in the behavior when

declarations. This patch does several things:

- Adds a test case making sure that conflicting 
  forward-declarations are resolved correctly;
- Extends the clang-import-test harness to test 
  two-level importing, so that we make sure we 
  complete types when necessary; and
- Fixes a few bugs I found this way. Failure to 
  complete types was one; however, I also discovered 
  that complete RecordDecls aren't properly added to 
  the redecls chain for existing forward 
  declarations.
